Feeling overwhelmed

Need advice from you mamas of multiples! I have a son that’s 2.5 and I’m 30 weeks pregnant (due in February) and I feel like I can’t take my son out anywhere. He has so much energy and literally won’t sit still and is into everything. Is this a boy thing???

Please tell me it gets better and he’ll chill out soon? Haha I just don’t know how I’m going to take out two kids in public when he’s pitching fits/having tantrums. I feel like I have to take him to a park to get his energy out before running errands.

Any advice or words of wisdom appreciated ❤️❤️
